These four different blood types result from different alleles of a single gene in the DNA These alleles give the directions for making different versions of a protein enzyme that puts different types of carbohydrate molecules on the surface of red blood cells Gives the directions for making a version of the enzyme that puts type A carbohydrate molecules on the surface of red blood cells puts type B carbohydrate molecules on the surface of red blood cells is inactive doesn t put either type of carbohydrate molecule on the surface of red blood cells Allele JA IB i 1 Each person has two copies of this gene one inherited from his her mother and the other inherited from his her father Complete the following table to relate genotypes to blood types Blood Type Genotype This person s cells make JA JA the version of the enzyme that puts type A carbohydrate molecules on the surface of red blood cells the inactive protein that doesn t put either type A or type B carbohydrate he surface of red molecules on the surface of red blood cells JAi both the version of the enzyme that puts type A carbohydrate molecules on the surface of red blood cells and the inactive protein 2 In a person with the I i genotype which allele is dominant I or i Explain your reasoning A
